Improving aging by therapy

Recent studies in mice show that older mice become healthier and have improved nervous system after being transfused from younger mice.

The results of these studies are expected to pave the way for further research to improve aging.

Saul Villeda, author of the study at the University of California (San Francisco), conducted experiments on mice equivalent to those in their 20s and 60s. The team continuously injected the old mice with the blood of other old mice or younger mice 's blood.

The animals injected with young mice had better performance when they tested their memory and cognitive abilities. For example, they remember the way back to a platform hidden in a labyrinth better than the ones that were injected with old mouse blood.

Villeda said the team is looking at what in the blood of young mice makes this difference.

Two other studies from Harvard University focused on a protein called GDF11 that is abundant in young rat blood than older mice. Amy Wagers, who participated in both studies, said the protein is also present in human blood and also decreases when people get older.

Harvard scientists also discovered that injecting young mice 'blood into older mice made blood vessels in the brain grow and help blood flow more.

The injection of GDF11 also has the same effect. Lee Rubin, a research author, said these results could help the following studies find ways to treat age-related neurological diseases, which may even cure human dementia. .

However, both Wagers and Villeda said it is not clear whether GDF11 is an explanation of Villeda's research results. Wagers also suggested that there may be other substances in the blood that can do this.
